Romney had the whole GOP on his side. He ran against an incumbent targeted for unprecedented hatred throughout his first term -- not even Nixon or Carter or W came in for such abuse! -- and burdened by an economy still in recession. He ran entirely on the Republican message -- necessitating much flip-flopping, since there is more than one Republican message, but he never colored outside the Party lines. He came nearer to beating Obama than Santorum, Gingrich or Paul could conceivably have done. The American people simply did not want any Republican in the WH this year.
